Dunlop tire codes

[Norman Golm]

I have 4 Dunlop tires I acquired with my recent purchase of TC 7677. They look perfect no cracks and the surface is soft enough so you can push your finger nail in. My concern is how old are they. There are 2 numerical markings on the tires, (3) have 61052 and (1) has 61053. There is another marking on each tire sup 01349, sup 06004, sup 01865, and sup 04902. Does anyone know if either of these are date codes and what is the code? By the way the Dunlop tubes are fine and they were holding air. Any help would be appreciated.
